Mynock

A mynock was a silicon-based parasitical organism found across the galaxy that was often seen leeching power from spacecraft. In addition, they could absorb matter from a ship's hull causing it to breach, and if not caught in time, cause catastrophic failure. Mynocks often attached themselves to passing starships to chew on power cables. A drop in the power of the hyperdrive could increase the travel time.[3] They were considered parasites by pilots and starport personnel, and failure to properly shake them off in orbit before landing could result in quarantine.
